Code 93

Code 93 is a variable-length linear barcode symbology, developed in 1982 and standardized in the AIM-BC5-2000 specification. It was designed to provide higher density and better security than the Code 39 symbology.

The data density is comparatively low, so it requires considerably more space to encode the same amount of data and can not be used to label smaller items.

A sample Code 93 barcode is shown below.
